🔍 Key Concepts

• Difference between true north, magnetic north, and compass north • Definition of variation vs deviation • Role of the magnetic meridian and geographic (true) meridian on charts and compasses

💭 Think About

• First, decide which two "north" directions variation deals with: is it about Earth’s magnetism, the ship’s compass errors, or both? • Ask yourself: does variation come from the Earth’s magnetic field, or from metal and electronics on your vessel? • Look at which choice mentions meridians that exist on the Earth itself (not inside the ship) and relate to magnetic vs geographic poles.

✅ Before You Answer

• Verify that variation is caused by the relationship between Earth’s magnetic field and true (geographic) north • Confirm that deviation (not asked here) relates to errors in the ship’s compass caused by local magnetic influences on board • Eliminate any option that talks about compass errors on the vessel rather than the Earth’s magnetic and geographic meridians
